If you are arrested for DUI/DAI in Pennsylvania you will be subject to two separate cases. The first case is the criminal court case where the prosecution will bear the burden of proving beyond a reasonable doubt that you committed the crime of “Driving Under the Influence” or “Driving After Imbibing.” If convicted you could face various criminal punishments such as probation, community service, mandatory alcohol rehabilitation and even jail time. The second case is the administrative or civil case with the Pennsylvania Department of Transportation. The sole issue with this case is your privilege to drive. This case is separate and independent from the criminal case and it is quite possible to be acquitted from the criminal charges and still have your license suspended or revoked through the Department of Transportation case.

With respect to the criminal case, the prosecution basically has two theories in which to prosecute the charges. First, the prosecution can bring the case under the “per se” theory and what this means is that if you submit to a blood-alcohol concentration test and the results show your blood-alcohol level to be .08% or higher, the prosecution will have met its burden in that case. This theory relies soley on your body chemistry and it makes no difference whether you were driving in a safe manner or showed any visible signs of being under the influence.

The second theory in which the prosecution can bring your case is the “under the influence” theory. Under this theory the prosecutor will usually introduce evidence such as the testimony of the arresting officer regarding your field sobriety tests, his or her observations regarding your driving pattern and appearance and any statements you may have made to the officer during your arrest. The prosecution may also introduce evidence of your blood-alcohol concentration and statements of eyewitnesses to prove your inability to safely operate your vehicle.

Pennsylvania Criminal DUI/DAI Law and Penalties

Pennsylvania’s drunk driving offenses are labeled driving under the influence (DUI), driving while impaired (DWI) or driving after imbibing (DAI).Pennsylvania has a three-tiered punishment system. The three tiers are broken down as follows: (1) the blood-alcohol content of .08% to .099%; (2) a blood-alcohol content of .10% to .159%; and (3) a blood alcohol content of .16% or higher.

The severity of the punishment in Pennsylvania is dependent upon two factors. The first factor is the blood-alcohol level upon your arrest and the second factor is whether or not the offense was your first or subsequent offense.



Like most states, when you’re arrested for DUI/DA I in Pennsylvania you will not only have to deal with the criminal case, but you also have to deal with the administrative case against the Pennsylvania Department of Transportation. This case is civil in nature and can only result in driver’s license suspensions. However, since the cases are separate it is possible to be acquitted of the criminal charges or have the charges dismissed and still have your license suspended pursuant to the administrative case.

The Department of Transportation has the power to suspend your license pursuant to Pennsylvania’s implied consent laws. When requested to take a blood-alcohol test you have the right to refuse such a test but this refusal results in a one-year loss of your driver’s license. The suspension may be appealed, but the appeal must be filed within 30 days of your suspension notice from the Pennsylvania Department of Transportation.
